(3) A failure to comply with the requirements of subsection (1) does not affect the validity of the decision.

(5) Subsection (4) does not apply in relation to claiming an amount as a debt if the person or estate has notified the Chief Executive Medicare as mentioned in subsection 56D(1A) in relation to the debt.
